NOAA publishes no 1991-2020 snowfall normal for this station. The nearest record that keeps one, Monroe (14 miles away), gets 3 inches of snow in a normal year; elevation and distance can change that.

When is the best weather to visit Everett?
Normal highs sit between 65°F and 85°F in June, July, August and September. Of those, July has the fewest days with rain (6).
That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in Everett?
In Everett, the last spring frost (32°F) comes after March 9 in half of years and after March 29 in one year in ten; the first autumn frost comes before November 17 in half of years and before October 31 in one year in ten.
Frost-free in half of yearsFrost in 1 to 9 years out of 10Frost most years
- Last spring frost, half of years after
- March 91 year in 10 after March 29; 9 in 10 after February 15
- First autumn frost, half of years before
- November 171 year in 10 before October 31; 9 in 10 before December 7
NOAA puts the median frost-free season at 250 days, and the season without a hard freeze (28°F) at 300 days.
A hard freeze (28°F) comes after February 13 in half of springs and before December 6 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Everett in zones 8b to 9a across its 5 ZIP code areas (8b in 98203, the largest). By the map's own method, the average of each year's coldest night over 1991-2020, Everett's NOAA station is in zone 9a: the coldest night of a typical year reaches 20°F (22 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Which places near Everett share this climate record?
24 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
